GEORGE N. CLEVELAND, OF FREELANDSVILLE, INDIANA.

'CORN-HARVESTER.

SPECIFICATION forming partof Letters Patent No. 500,055, dated June 20,1893. Application filed May 28, 1892. Serial No. 434,782. [No model.)

To all whom it may concerm Be it known that I, GEORGE N. CLEVELAND, acitizen of the United States, residing at Freelandsville, in the countyof Knox and State of Indiana, have invented certain new and usefulImprovements in Corn-Harvesters,

View looking toward the right from the dot' ted line 3 3 in Fig. 1; Fig.4 a detail view of one of the adjustable boxes carrying the largerwheel; Fig. 5 a detail sectional view of the adjustable box carrying thesmaller wheel, and Fig. 6 a detail horizontal sectional view lookingdownwardly from the dotted line 6 6 in Fig. 3.

i In said drawings the portions marked A represent the frame-work of themachine; B and O the smaller and larger carrying wheels, respectively; Dan intermediate shaft driven from the shaft of the larger wheel; E thevertical shaft to the cutter and reel; F a rotating bar, which is themain member of the rack for receiving the corn as cut, and G the thillsor shafts whereby the machine is drawn.

The frame A is of suitable form to carry the mechanism, a preferred formbeing illustrated in the drawings. It is provided with bearings andsupports for such mechanism, as will be explained in connection with thedescription thereof. Standards S extend up from this frame near thereel, and a guidebar S, of a form to aid the reel in gathering in thecorn, is mounted thereon.

The smaller wheel B is mounted on a bearing block B, which is verticallyadjustable in a preferably dovetailed groove or way in the adjacentportion of the frame A. The adjustability is provided for so that thecutting mechanism may be positioned nearer to or farther from the rootsof the corn being out, according to circumstances.

The wheel 0 is larger than the wheel B, is fast on its axle, and carriesthe greater portion of the weight of the machine, and of the driver. Atoothed pinion c is mounted on its driven.

axle O by means of which the mechanism is Said axle is mounted inadjustable bearings c 0 which are carried in segment: shaped ways ct aon the frame-work, whereby this side of the machine may be raised orlowered in positioning the cutting apparatus.

The shaft D has a pinion d by which it is driven from the pinion c onthe axle 0'. At the other end it has a beveled gear wheel 61 whichengages with a similar wheel on the shaft E, and thus drives said shaftand its mechanism.

The shaft E is arranged in a verticalposition, with its lower endstepped into a bearing 0. in the cross bar A of the frame-work, and itsupper endv supported by a bearing a in the upper end of the bracket Awhich is mounted on said frame-work, and extends up wardly, as shown.Near the lower end it carries the beveled gear Wheel 6, by which it isdriven from a similar wheel 61' on the shaft D; and below that isarranged a circular cutting knife or sickle E. Said cutting knife iscircular in form, with blades somewhat similar to saw teeth. The cuttingedges of these bladesare so inclined that when they come near to thestationary blade A below them,

in the final act of cutting, their points will be very slightly closerto said blades than their heels. They naturally force the stalks to becut, somewhat to one side before actually cutting them, and this,together with the action of the reel, as will be presently explained,gives a shearing direction to the out, which is more certain, andrequires somewhat less 'power than a direct cross-cutting movement.

There are two blades A and A secured upon the cross bar A of theframe-work directly below this cutter or sickle, which diverge from eachother, and thus serve to gather the corn stalks to the apex, where theycome in contact with said sickle and are cut. The blade A has asharpened edge directly at the point where the sickle operates, whichaids in the cutting operation. At the upper end of the shaft E is a reelcomposed of a hub, a I

greater extent than they are by said sickle and so, when said stalks arebrought around to position for cutting, the ring and arms aid insecuring the slanting direction most' desirable for the shearing out, asabove stated.

This reel may be adjusted up and down on the shaft E by means of thehand-leverE or otherwise, so that it will operate more efficiently withthe varying heights of stalks, it

being, of course, adjusted nearer the top ofthe shaft for the higherstalks, and farther down for the shorter ones. Above the knife or sickleE and surrounding the gear wheel e' constitutes a part of theframe-work, and which extends out parallel with the" bar F, also hasarms a similar to the arms f which extend up and form the other side ofthe rack. Upon the end of the bar F is an arm J from which a connectingrod f runs forward and connects with the lever (preferably foot-lever) FThe operation is, when the desired quantity of stalkshave been cut anddeposited in the rack; that the driver releases the lever F permittingthe bar F to rock in its bearings, which dumps the corn contained in therack onto the ground. If desired, a laborer may come up behind themachine and lift the corn from the rack in his arms, instead of havingit dumped onto the ground, as above de- 118th day of May, A. D; 1892.

The shafts G are similar in general form to those for many kinds ofvehicles. They are scribed.

secured to the frame-work A by the pivots 9.

They extend back, however, beyond said pivadjusted to suit the varyingheights ofani mals that draw the machine.

The machine as a whole is a simple and effective device for the purpose,requiring only a comparatively moderate amount of power to drive it, andit is easily kept in order, and adjusted to the required uses..

Having thus fully described my said invention, what I claimas new,anddesire to secure I by Letters Patent, isextend up therefrom. Thetimber A which i The combination, in a corn harvester, of the uprightshaft E carrying the rotary sickle upon the lower end, the two blades AA se-' cured to the frame-work and converging toward the cutting pointof said sickle, to one side of the shaft, a reel upon the upper end ofthe shaft, composed of arms, anda ring or center larger than the sickle,whereby the stalks are pushed outwardly toenable said sickle to have ashearing out, and a guide S mounted upon standardsiand curved to guidethe stalks between the arms of the reel and.

around to the rearthereof onto the dropper, said several parts beingarranged and operating substantially asshown and described.

In witness whereof Ihavehereunto set my hand and seal, at Indianapolis,Indiana, this GEORGE N. CLEVELAND. .[L. s.]' Witnesses:
